maXTouch Xplained Pro
=====================
Connectivity
------------
Testing has also been performed using the maXTouch Xplained Pro LCD
(ATMXT-XPRO). That LCD could be connected either via EXT1 or EXT2 using the 2x10
20-pin cable and the maXTouch Xplained Pro standard extension header. Access
this then performed in SPI mode.
(ATMXT-XPRO).
maXTouch Xplained Pro Standard Extension Header
-----------------------------------------------
The LCD could be connected either via EXT1 or EXT2 using the 2x10 20-pin
cable and the maXTouch Xplained Pro standard extension header. Access is
then performed in SPI mode.
NOTE the 3 switch mode selector on the back of the maXtouch. All switches
should be in the ON position to select 4-wire SPI mode.

NOTE: Use of EXT1 conflicts with the Arduino RXD pin (PD28). You cannot
put the maXTouch Xplained in EXT1 and also use the Arduion RXD/TXD pins
put the maXTouch Xplained in EXT1 and also use the Arduino RXD/TXD pins
as your serial console.
It ought be possible to connect the LCD via the flat cable to the EXT4 LCD
connector. In this case, you would use the SMC to communicate with the LCD.
I have not tried this configuration.

It is also possible to connect the LCD via the flat cable to the EXT4 LCD
connector. In this case, you would use the SMC/EBI to communicate with the
LCD.
Configuration Options
---------------------
NOTE: (1) Only the RGB interface is supported by the SAMV71-XULT and (2) the
3 switch mode selector on the back of the maXtouch. These switches should be
in the OFF-ON-OFF positions to select 16-bit color mode.
